High-efficiency and low-cost 400W power supply design based on ADP1051

This reference design uses the ADP1051, a newly launched low-cost and highly integrated power supply chip from ADI, to control the energy conversion from input to output. This power supply design comprehensively considers factors of efficiency and cost, and designs a solution with optimal efficiency and cost at the 400W power level. It is suitable for power amplifier power supply systems of wireless communication base stations and railway power supply systems in the industrial field. The ADP1051 is a digital controller with PMBus interface for isolated power supplies. Due to the excellent performance of ADP1051, this design features high reliability, high efficiency, and high integration. In addition, this reference design also implements a series of monitoring functions, such as IOUT_OC, VOUT_OV, OT, VOUT_UV defined in PMbus, input UVLO, reverse current protection, short circuit protection, etc.
